Porifera
Porifera, also known as sponges are among the most simple animals. They are usually very colorful as seen in the picture below. These animals are mostly aquatic and there are predicted to be over 15,000 species. The word Porifera means "pore bearing", this is because every sponge is surounded by pores that allow water to flow through them. (think osmosis!) These are some important features of a sea sponge (Write these as your notes, not the in depth decriptions)
They feed by filteration
They have a different types of cells
They have no internal organs.
They have a network of microscopic crystals or fibers that act as an internal skeleton.
They are asymetrical
Reproduction can be asexual or sexual
There are three types of sponge stuctures. 1.Asconoid 2.Syconoid 3.leuconoid
Are intervertabrates
These 4 characteristics are the main features of Sponge, they will be disscussed in more depth in the following sentances.]
CLASSIFICATION: The classification of a Porifera is
FILTERATION: Sponges have a unique type of cell, not found in the other animal phylum called a choanocyte also known as, collar cells. This unique cell is used in the feeding process of the sponge. The collar cells inside the pores of the sponge create water that is used to create an available food source for the sponge. By pumping the water they can get food source that float around the sponge. They are filter feeders.
SPONGE STRUCTURES
Asconoid sponges are shaped like a simple tube with pores
An Asconoid Sponge
Asconoid
Syconoid sponges: Are lager with more tubular bodies
Syconoid
Leuconoid sponges:These are the most complex and contain tissue and canals.
<--A Leuconoid Syconoid---> Use Spongebob as a reminder that Porifera is a sponge. Also Sponges are made of pores so PORifera Multible Choice:

They have a complex organs similar to our stomach.
The use filteration and move food through their pores.
